NeXpy provides a high-level python interface to NeXus data contained within a simple GUI. It is designed to provide an intuitive interactive toolbox allowing users both to access existing NeXus files and to create new NeXus-conforming data structures without expert knowledge of the file format.

See the NeXpy documentation for more details.

Released versions of NeXpy can be installed using either

    $ pip install nexpy

or

    $ easy_install nexpy 

The source code can be downloaded from the NeXpy Git repository:

    $ git clone https://github.com/nexpy/nexpy.git

To install in the standard Python location:

    $ python setup.py install

To install in an alternate location:

    $ python setup.py install --prefix=/path/to/installation/dir

The following libraries are used by the full installation of NeXpy. There is more details of the nature of these dependencies in the NeXpy documentation.

• h5py http://www.h5py.org
• numpy,scipy http://numpy.scipy.org
• iPython v1.1.0 http://ipython.org/
• PySide v1.1.0 http://www.pyside.org/

• lmfit http://newville.github.io/lmfit-py (Fitting only)
• pycbf http://www.bernstein-plus-sons.com/software/CBF/ (CBF reader only)
• spec2nexus http://spec2nexus.readthedocs.org (SPEC reader only)

The following environment variable may need to be set PYTHONPATH --> paths to ipython,numpy,scipy,matplotlib if installed in a nonstandard place

All of the above are included in the Enthought Python Distribution v7.3.

To run from the installed location, add the $prefix/bin directory to your path (only if you installed outside the python installation), and then run:
